Engineers achieve record-breaking battery performance
Engineers at Monash University have developed a new catalyst that could drive zinc-air batteries from hearing aids and watches to EVs and large-scale industrial applications. While zinc-air batteries are currently used in small devices, this opens the door to rechargeable, high-power applications, moving the technology closer to real-world, grid-scale and transport uses. Using microscopic heat treatment, the researchers have developed carbon sheets from 3D materials, adding a framework of individual cobalt and iron atoms to greatly increase reactivity and efficiency within the battery. Saeed Askari and Dr Parama Banerjee, lead authors from Monash University’s chemical and biological engineering department, say the breakthrough catalyst outperformed standard commercial catalysts made from expensive metals like platinum and ruthenium. “By engineering cobalt and iron…
